Sr. Engineer, Actuation Systems Embedded Software

RTX•Huntsville, AZ

2d•Onsite

About The Position

The PCAS department is seeking an embedded software/firmware engineer to support development of a range of high-performance actuation systems, such as aerodynamic steering, thrust vectoring, attitude and divert maneuvering, pointing, and stabilization of missile systems & subsystems. This is an onsite role: Tucson, AZ or Huntsville, AL or Portsmouth, RI. You will help specify, design, verify, and integrate motor control embedded firmware for current and future precision control actuation systems. You will implement digital control algorithms in C/C++ in conjunction with the Controls and Algorithms team. Day-to-day the candidate will be expected to apply sound engineering practices to address technical problems while collaborating with a team including electrical engineering, mechanical engineering, control systems engineering, test engineering, systems safety engineering, and others.

Requirements

Requires a University Degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 5 years of prior relevant experience or an advanced degree and minimum of 3 years of prior relevant experience.
Systems engineering design and/or development or experience working in a disciplined, controlled manner, fully documenting work; extensively commenting code, test benches and test software.
Experience with C/C++ development on embedded hardware platforms or similar.
Experience with model development and/or data analysis in MATLAB/Simulink.
Active and transferable U.S. government issued security clearance is required prior to start date.
U.S. citizenship is required.
